CHAPTER 1

1.1About the Gateway

The Gateway provides Internet access to multiple users by sharing a single-user account. The Gateway's most outstanding features include wireless LAN connectivity, as well as the dual-port WAN interface which allows you to connect to an xDSL or Cable modem, ISDN TA or PSTN analog modem. The Gateway provides extensive firewall protection and Virtual Private Network (VPN) services. It also provides print services for any client attached to a LAN port.

The Gateway supports dial-on-demand for ISDN/PSTN service, automatically connecting to the Internet when there are requests, and terminating the connection if no further requests occur. This dual-port design also supports fail-over Internet access through the secondary WAN port (i.e., the serial port can be used for primary or backup Internet access).

This new Gateway technology provides many cost-effective functions and management benefits. It is simple to configure and can be up and running in minutes.

CHAPTER 1

1.3Applications

Many advanced applications are provided by the Gateway, such as:

zFlexible LAN Access

The Gateway provides connectivity to 10/100 Mbps wired devices as well as 11 Mbps wireless mobile users. The wireless interface makes it easy to create a network in dif- ficult-to-wire environments, or to provide quick access to databases for mobile workers.

zInternet Access

This device supports Internet access through an xDSL, Cable, ISDN or PSTN connection. Since many xDSL providers use PPPoE to establish communications with end users, the Gateway includes a built-in client for this protocol, eliminating the need to install this service on your computer.

zShared IP Address

The Gateway provides Internet access for up to 253 users with a shared IP address. Using only one ISP account, multiple users on your network can browse the Web at the same time.

zVirtual Server

If you have a fixed IP address, you can set up the Gateway to act as a virtual host for network address translation. Remote users access various services at your site using a constant IP address. Then, depending on the requested

1-4

service (or port number), the Gateway can route the request to the appropriate server (at another internal IP address). This secures your network from direct attack by hackers, and provides more flexible management by allowing you to change internal IP addresses without affecting outside access to your network..

zUser-Definable Application Sensing Tunnel

You can define special applications that require multiple connections such as videoconferencing, Internet gaming, and Internet telephony. The Gateway can then sense the application type and open a multi-port tunnel for it.

zDMZ Host Support

Allows a networked computer to be fully exposed to the Internet. This function is used when the special application sensing tunnel feature is insufficient to allow an application to function correctly.

zSecurity

The Gateway supports security features that can deny Internet access to specified users, or filter all requests for specific services the administrator does not want to serve. The Gateway's firewall can also block common hacker attacks, including IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding.

zVirtual Private Network

The Gateway supports three of the most commonly used

1 CHAPTER

1-5

CHAPTER 1

VPN protocols - PPTP, L2TP and IPSec. These protocols allow remote users to establish a secure connection to their corporate network. If your service provider supports VPNs, then any of these protocols can be used to create an authenticated and encrypted tunnel for passing secure data over the Internet (i.e., a traditionally shared data network). The VPN protocols supported by the Gateway are briefly described below:

*Point-to-Point Tunneling Protocol: Provides a secure tunnel for remote client access to a PPTP security gateway. PPTP includes provisions for call origination and flow control required by ISPs.

*Layer Two Tunneling Protocol - Includes most of the features provided by PPTP, but has fewer overheads and is more suited for managed networks.

*IP Security - Provides IP network-layer encryption. IPSec can support large encryption networks (such as the Internet) by using digital certificates for device authentication

2.2 Description of Hardware

The main functions of the Gateway can be divided into three categories:

1.Connects to the Internet or to a remote site by using its RJ-45 WAN port or RS232 serial port.

2.Directly connects to your PC or to a local area network by using any of the three Fast Ethernet LAN ports or through the IEEE802.11b wireless interface.

3.Functions as a print server as well.

Access speed to the Internet depends on your service type. Full-rate ADSL can provide up to 8 Mbps downstream and 640 Kbps upstream. G.lite (or splitterless) ADSL provides up to 1.5 Mbps downstream and 512 Kbps upstream. Cable modems can provide up to 36 Mbps downstream and 2 Mbps upstream. ISDN can provide up to 128 Kbps when using two bearer channels. And PSTN analog connections can now run up to 56 Kbps. However, you should note that the actual rate provided by specific service providers may vary dramatically from those above-mentioned limits.

Although access speed to the Internet is determined by the modem type connected to your Gateway, data passing between devices connected to your local area network can run up to 100 Mbps over the Fast Ethernet ports.

The Gateway includes an LED display on the front panel for system power and port indications that simplifies installation and network troubleshooting. It also provides three RJ-45 LAN ports, one RJ-45 WAN port, one RS232 serial

port, one parallel printer port, as well as two antennas on the rear panel.

zThree RJ-45 ports for connection to a 10BASE- T/100BASE-TX Ethernet Local Area Network (LAN). These ports can auto-negotiate the operating speed to 10/100 Mbps, the mode to half/full duplex, and the pin signals to MDI/MDI-X (i.e., allowing these ports to be connected to any network device with straight-through cable). These ports can be connected directly to a PC or to a server equipped with an Ethernet network interface card, or to a networking device such as an Ethernet hub or switch.

zOne RJ-45 port for connection to an xDSL or Cable modem. This port is fixed at 10 Mbps, full duplex.

zOne RS232 serial port to connect to an ISDN Terminal Adapter (TA) or to a PSTN analog modem.

zOne parallel printer port that can be connected to a printer, which can be shared by any LAN/WLAN users.

2.4.2Attach to Your Network Using Ethernet Cabling

The three LAN ports on the Gateway can auto-negotiate the connection speed to 10 Mbps Ethernet or 100 Mbps Fast Ethernet, as well as the transmission mode to half duplex or full duplex. These LAN ports also support auto-configura- tion for pin signals (auto-MDI/MDI-X) that allows you to use straight-through cable for connecting the Gateway to any network device. (See Appendices "B. Cables" for details on wiring.)

Use twisted-pair cable to connect any of the three LAN ports on the Gateway to an Ethernet adapter on your PC. Otherwise, you can cascade any of LAN ports on the Gateway to an Ethernet hub or switch, and then connect your PC or other network equipment to the hub or switch. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated.

Warning:

Do not plug a phone jack connector into any RJ-45 port. This may damage the Gateway. Instead, use only twistedpair cables with RJ-45 connectors that conform to FCC standards.

2 CHAPTER

2-9

CHAPTER 2

Notes:

1.Use 100-ohm shielded or unshielded twisted-pair cable with RJ-45 connectors for all connections. Use Category 3, 4 or 5 for connections that operate at 10 Mbps, and Category 5 for connections that operate at 100 Mbps.

2.Make sure each twisted-pair cable does not exceed 100 meters (328 feet).

Figure 2-3 Making LAN Connections

2-10

2.4.3 Attach to Your Network Using Radio Signals

Install a wireless network adapter in each computer that will be connected to the Internet or your local network via radio signals.

Rotate both antennas on the back of the Gateway to the desired position. Try to place the Gateway in a position that is located in the center of your wireless network. Normally, the higher you place the antenna, the better the performance will be. Ensure that the Gateway's location provides optimal reception throughout your home or office.

Computers equipped with a wireless adapter can communicate with each other as an independent wireless LAN by configuring each computer to the same radio channel. However, the Gateway can provide access to your wired/wireless LAN or to the Internet for all wireless workstations. Each wireless PC in this network infrastructure can talk to any computer in the wireless group via a radio link, or access other computers or network resources in the wired LAN infrastructure or over the Internet via the Gateway.

The wireless infrastructure configuration not only extends the accessibility of wireless PCs to the wired LAN, but also doubles the effective wireless transmission range for wireless PCs by re-transmitting incoming radio signals through the Gateway.

A wireless infrastructure can be used for access to a central database, or for connection between mobile workers, as

CONFIGURING CLIENT TCP/IP

To access the Internet through the Gateway Broadband Router, you must configure the network settings of the computers on your LAN to use the same IP subnet as that defined for the Gateway. The default network settings for the Gateway are:

IP Address: 192.168.2.1

Subnet Mask: 255.255.255.0

Note:These settings can be changed to fit your network requirements, but you must first configure at least one computer as described in Chapter 3 "Configuring Client TCP/IP" to access the Gateway's Web configuration interface. (See Chapter 4 "Configuring the Gateway" for information on configuring the Gateway.)

All PCs connected to the Gateway must be set to the same IP subnet as the Gateway. The default subnet address of the Gateway is 192.168.2.X (where X means 2-254) and the subnet mask is 255.255.255.0. You can set the IP address for client PCs either by automatically obtaining an IP address from the Gateway's DHCP service or by manual configuration. See Section 3.2 "Setting TCP/IP to Work with the Gateway".
